Guillaume Delisle

Delisle, Guillaume (gēyōmˈ dəlēlˈ) [key], 1675–1726, French geographer and cartographer. His most important work is a world map (1700), as accurate as the data available at that time permitted and the first map on which the errors of Ptolemy were wholly absent. Delisle is called the founder of modern cartography. He was geographer to Louis XV.
